Best Oil for the BMW E92 (N52, N54, N55)
For the N52, N54 and N55, the answer is a quality BMW Longlife-01 (LL-01) 5W-30 full synthetic — but the turbos run hot and reward a robust oil, and the M3's V8 is a different beast entirely. Here's the right oil for your engine, and the products we'd actually buy.

The Right Oil, by Engine
Match the spec first — then pick a brand below.
| Engine | Found in | Spec | Viscosity | Approx capacity |
|---|---|---|---|---|
| N52 / N51 | 325i / 328i / 330i | LL-01 | 5W-30 | ~6.5 qt |
| N54 | 335i (2007–2010) | LL-01 | 5W-30 (5W-40 when tuned) | ~6.9 qt |
| N55 | 335i (2011+) | LL-01 | 5W-30 | ~6.9 qt |
| N20 | 328i (2012–2013) | LL-01 | 5W-30 | ~5.3 qt |
| Diesels (N47 / M57) | 320d–335d | LL-04 | 5W-30 | varies |
| S65 (M3) | M3 V8 | BMW M (10W-60) | 10W-60 | ~9 qt |
Capacities are with-filter approximations — trust the dipstick over the bottle count, and confirm your engine's figure.
For the three engines in the title, it's simple: a full-synthetic LL-01 5W-30 meets BMW's specification and is the right everyday choice for the N52, N54 and N55. The nuance is the turbos — see the tuned-and-tracked note below — and the M3, which needs a 10W-60 entirely.
M3 owners: 10W-60, not LL-01
The biggest mistake on this page would be pouring a 5W-30 into an S65. The M3's V8 has bearing clearances built around a heavier 10W-60, so it needs the M-spec oil — the same family the E46 M3's S54 used. Match the oil to the engine and it'll thank you.
FAQ
What oil does my E92 take?
For the N52, N54 and N55, a full-synthetic BMW LL-01 5W-30. The N20 also takes LL-01 5W-30. The diesels need LL-04, and the M3's S65 V8 needs a 10W-60 M-spec oil. Always check the bottle carries the right approval.
Can I run 5W-40 in my N54 or N55?
Yes — an LL-01 5W-40 is a common choice for tuned or track-driven turbos, giving a touch more high-temperature protection than 5W-30. For a stock daily driver, the factory 5W-30 is correct.
How often should I change the oil on a 335i?
BMW's interval can stretch long, but the N54 and N55 run hot and suffer fuel dilution, so many owners change every 5,000 miles. Shorter, more frequent changes are cheap insurance on a turbo engine.
Does the M3 really need 10W-60?
Yes. The S65 V8's bearing clearances were designed around a 10W-60 M-specification oil, just like the E46 M3's S54. Running a thin LL-01 in it isn't recommended — use the correct 10W-60.
LL-01 or LL-04 — what's the difference?
LL-01 is the standard Longlife approval for the E92's gas engines. LL-04 is a low-SAPS oil for diesels and certain markets with particulate filters. For an N52/N54/N55 in most markets, LL-01 is the one you want.
The Bottom Line
For the N52, N54 and N55, run a quality LL-01 5W-30 full synthetic — Liqui Moly is our pick, with Castrol EDGE a proven alternative — and change it on the early side if your turbo is tuned or tracked. Step to an LL-01 5W-40 for a hard-driven 335i, give the M3 its 10W-60, and feed the diesels LL-04. Ready to do the job?
